    Abstract : New methodologies and concepts for developing compact and energy efficient automotive exhaust systems have been studied. This originates in the growing concern for global warming, to which road transportation is a major contributor. READ MORE

  3. 3. Active Noise Control in Ventilation Systems Practical Implementation Aspects

    University dissertation from Karlskrona : Blekinge Institute of Technology

    Author : Martin Larsson; Blekinge Tekniska Högskola.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : In many kinds of buildings, the ventilation is handled by a mechanical ventilation system. Such ventilation systems constitute a well known source of broadband noise. READ MORE

  4. 4. Mating type switching and transcriptional silencing in Kluyveromyces lactis

    University dissertation from Stockholm : The Wenner-Gren Institute, Stockholm University

    Author : Emad Barsoum; Stockholms universitet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mating type switch; transcriptional silencing; alpha3; transposase; Ume6; Mts1; Ras; cAMP; K. lactis; NATURAL SCIENCES Biology Organism biology Developmental biology; NATURVETENSKAP Biologi Organismbiologi Utvecklingsbiologi; Developmental Biology; utvecklingsbiologi;

    Abstract : To explore the similarities and differences of regulatory circuits among budding yeasts, we characterized the role of unscheduled meiotic gene expression 6 (UME6) and a novel mating type switching pathway in Kluyveromyces lactis. We found that Ume6 was required for transcriptional silencing of the cryptic mating-type loci HMLα and HMRa. READ MORE

  5. 5. Silencing and DNA double-strand break repair in budding yeast

    University dissertation from Stockholm : Wenner-Grens institut för experimentell biologi

    Author : Andreas Kegel; Stockholms universitet.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Silencing; Reb1; DSB; NHEJ; Nej1; illegitimate recombination; yeast; NATURAL SCIENCES Biology Organism biology Developmental biology; NATURVETENSKAP Biologi Organismbiologi Utvecklingsbiologi;

    Abstract : Transcriptional silencing that makes large chromosomal domains inaccessible for the transcriptional apparatus is nucleated at DNA elements called silencers. In K.lactis a 102bp HMLα silencer was defined revealing three distinct protein-binding regions (A, B, and C) that were required for silencing of HMLα. READ MORE
